CNOOC Ltd. stock (ISIN HK0883013259) ended the September 18, 2026 session on the Hong Kong Stock Exchange lower at HKD 23.60, a decline of 1.173 percent from the prior close despite strong interim earnings momentum.

Interim 2026 results show double-digit growth

According to etnet, CNOOC reported profit attributable to shareholders of HKD 10,568,000 thousand for the interim period of 2026, with the result labeled as the 2026 year interim announcement, and this represents a 24.052 percent increase compared with the same period a year earlier.

In the same interim 2026 disclosure, earnings per share were stated at HKD 8.360, while net book value per share stood at HKD 47.842, underlining that the offshore producer enters the second half of 2026 with a solid equity cushion and improved profitability compared with the prior year period.

Stock performance and financing activity

Per data from etnet, the Hong Kong-listed CNOOC shares, traded under code 00883, closed at HKD 23.60 on September 18, 2026, reflecting a 1.173 percent decline for that trading day, with the quote marked as last updated at 16:40 local time, and the move coming despite the positive interim profit trend reported for 2026.

As Sina Finance reported on September 19, 2026, the A-share of China National Offshore Oil, the mainland listing of CNOOC, fell 0.83 percent on September 18, 2026, on turnover of CNY 1,111,000,000, while margin financing buy volume reached CNY 90,330,900 and margin repayment volume was CNY 95,720,900, leaving a net margin outflow of CNY 5,390,000.

According to the same margin financing overview from Sina Finance, the financing balance on September 18, 2026 stood at CNY 2,190,598,100, corresponding to 2.27 percent of CNOOC’s free-float market value, a level described as exceeding the 70 percent percentile over the past year and indicating relatively high investor participation through margin trading.

Investor takeaways and valuation context

For investors, the combination of a 24.052 percent year-on-year increase in interim profit attributable to shareholders and an earnings per share of HKD 8.360 for the interim 2026 period suggests that CNOOC is delivering robust earnings growth from its offshore oil and gas portfolio while the Hong Kong share price at HKD 23.60 as of September 18, 2026 does not fully reflect the fundamental improvement implied by the double-digit profit expansion.

With net book value per share at HKD 47.842 in the interim 2026 disclosure, the closing price of HKD 23.60 on September 18, 2026 positions CNOOC stock at a substantial discount to its stated book value, offering investors a valuation perspective where the shares trade at roughly half of the accounting equity per share, based on the figures cited by etnet for the interim 2026 period.

Current price level and market perspective

As of the close on September 18, 2026, CNOOC Ltd. stock on the Hong Kong Stock Exchange traded at HKD 23.60, with the day’s move showing a 1.173 percent decline from the previous close, and the valuation standing significantly below the interim 2026 net book value per share of HKD 47.842 that underpins the company’s balance sheet strength.
